Description

Tissue traction device without occupying laparoscopic channel

Technical Field

The utility model relates to the field of medical equipment, in particular to a tissue traction device which does not occupy a laparoscopic channel.

Background

Laparoscopic surgery (laparoscopic surgery) is a surgical procedure that may provide less risk, less patient trauma, and/or reduced surgical time. In a typical laparoscopic procedure, 3-5 channels are routinely required. The surgeon performs the procedure on the target tissue using laparoscopic surgical instruments through these channels, often requiring the gallbladder or other organ to be pulled for exposure during any laparoscopic procedure.

However, exposing tissue often requires more than two instruments, but clinically requires access to perform other procedures simultaneously, and thus often experiences insufficient access, increased access to the tissue increases surgical trauma, and limitations in the space between the inside and outside of the laparoscopic procedure do not allow for unlimited access. In particular, the surgical technique is developing from minimally invasive to ultra-minimally invasive, and in clinical practice, single Kong Shoushu is rapidly developing, single-hole laparoscopic surgery is performed by guiding 2-3 instruments through a small hole, the operation space left for a surgeon in vitro and in vivo is smaller, and single Kong Fuqiang mirrors are more difficult to expose tissues due to the chopstick effect, so that a multidirectional automatic traction device which does not occupy channels is more needed. For this reason, a new instrument is urgent to solve the above problems.

Detailed Description

All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.

Example 1

As shown in fig. 1 and 2, the main structure of the present embodiment is a gripping clip, which includes an upper and a lower clamping plates 1, where the clamping plates 1 are relatively connected by an elastic component 2, so that the gripping clip has a certain clamping force. One end of the grabbing clamp is a clamping end, opposite surfaces of two clamping plates of the clamping end are clamping surfaces 6, a plurality of convex teeth are arranged on the surfaces of the clamping surfaces 6, and the contact area of the clamping surfaces is increased, so that the clamping effect is improved. The clamping end surfaces of the two clamping plates 1 are provided with convex parts 8 which are arranged to be convex in pairs, and the surfaces of the convex parts are provided with a plurality of convex teeth (the convex teeth comprise a conventional sawtooth structure, a smooth tooth structure, a strip tooth structure and the like), so that the clamping effect is further improved

On the other end face of the clamping plate 1, an inward sinking concave hole 7 is formed along the extending direction of the clamping plate, the concave hole 7 is used for placing a needle 3, one end of the needle 3 is connected with a traction wire 4, and the other end of the traction wire 4 is fixedly connected to an anchor point 5 on the clamping plate 1. As shown in fig. 3, the structure of the needle 3 in this embodiment is different from the conventional needle in that one end of the needle body 3-1 is a needle tip 3-2, a through hole 3-3 is provided in the needle body 3-1 at the lower end of the needle tip 3-2, the through hole 3-3 is used for passing through and fixing the pull wire 4, the other end of the needle body 3-1 is a tail portion of the needle, and the tail portion is an enlarged structure 3-4.

In the present embodiment, the number of needles 4 and pull wires 4 can be adjusted according to the actual pull direction. When traction is only required in one direction, only one needle 3 may be provided on the grip block 1; when the position of the tissue to be retracted needs to be adjusted, at least two needles 3 and retraction wires 4 need to be provided for retraction in both directions. In the use process, the needle 3 and the traction wire 4 penetrate through the abdominal wall, the tail part of the needle 3 is reserved in the abdominal cavity, the purpose of the expanding structure 3-4 is to prevent the needle 3 from completely penetrating out of the abdominal cavity, in the operation process, in order to change the traction direction, the needle 3 can be withdrawn in the abdominal cavity, meanwhile, the needle 3 drives the traction wire 4 to return from the original path, and puncture is found in the abdominal cavity again for traction. Of course, after the operation is finished, the needle 3 can be forcibly pulled out of the body by pulling the insertion needle out by a large force.

As shown in fig. 4, in the actual use state of the present embodiment, four needles 3 and traction wires 4 are adopted in the present embodiment, after the visceral tissue C is clamped by the grasping clips a, the surgical instrument is used to drive the needles 3 to pass through the abdominal wall B, and the other ends of the traction wires 4 are fixed by the hemostatic forceps E outside the abdominal cavity, so as to complete the traction of the visceral tissue C. Since the surface of the tissue to be pulled is under tension in the actual operation, the pulling strength of the pulling wire 4 needs to be adjusted in order to prevent the tension from disappearing in the operation cutting, and therefore, in general, a spring D is provided on the surface of the abdominal wall B, and the pulling wire 4 is wound around the spring D to block the disappearance of the surface tension of the pulled visceral tissue C by the elastic force.

Example two

As shown in fig. 5 and 6, the expansion is performed on the basis of the first embodiment. In practice, because the diameter of the opening in the abdominal cavity is limited, only small-sized instruments are allowed to enter the abdominal cavity, while a large clamping surface is required to clamp the tissue inside the abdominal cavity.

The present embodiment thus adopts a scheme in which the main grip clamp a and the sub-grip clamp F are used in combination, wherein the clamping structure of the sub-grip clamp F is the same as that of the main grip clamp a. The only difference is that the primary grip clamp a is provided with a needle and a pull wire, while the secondary grip clamp F is not provided with a needle and a pull wire. Grooves are formed in the side faces of the clamping plates of the main clamping clamp A, buckles are arranged on the side faces of the clamping plates of the auxiliary clamping clamp F, and the buckles are matched with the grooves to form buckle assemblies 9, so that the main clamping clamp A is fixedly connected with the auxiliary clamping clamp F.

The main gripping clamp A and the auxiliary gripping clamp F keep the same direction of the clamping ends, so that the main gripping clamp A and the auxiliary gripping clamp F can simultaneously clamp visceral tissues, and the traction wire is utilized to traction the main gripping clamp A and simultaneously drive the auxiliary gripping clamp F to traction.

The utility model is not limited to the specific embodiments described above. The utility model extends to any novel one, or any novel combination, of the features disclosed in this specification, as well as to any novel one, or any novel combination, of the steps of the method or process disclosed.
